A supermassive black hole has torn apart a star and is now using its remains to pummel another star orbiting the black hole at a safe distance 1. The black hole, one million times heavier than the ...

Researchers have identified a black hole that appears to have come into being through the collapse of the core of a large star in its death throes, but without the usual blast. It was observed ...

A massive black hole has torn apart one star and is now using that stellar wreckage to pummel another star or smaller black hole that used to be in the clear. This discovery, made with NASA's ...

The black hole, V404 Cygni, was already known to be circled by a nearby star every 6.5 days. It is likely stripping this stellar companion of matter. (Image credit: NASA's Scientific Visualization ...

"Overall, it's not surprising that black holes should be in triples, but what's surprising is that this system held onto the outer star after forming the black hole." Astronomers have discovered ...

Stellar-mass black holes typically form after a star goes supernova and collapses. However, the discovery of the first-ever triple black hole system, V404 Cygni, complicates that picture.

By Dennis Overbye Just in time for Halloween, two black holes are in the news. One is a serial killer, on the verge of devouring its second star in five years. The other is part of what ...

The system, called V404 Cygni, was thought to be a black hole and a companion star, but a second star billions of kilometres away was also found to be gravitationally connected to the duo.
